OPERATION
CAUTION: Unauthorized modification of the feeder or use of unauthorized replacement parts may damage the
feeder.
L-R Systems will not assume responsibility for feeder performance as a result of any unauthorized
alterations to the equipment. Consult L-R Systems, Material Handling Solutions before modifying your
feeder.
With the feeder and controller properly installed and all wiring completed, the equipment is ready for
operation.
WARNING: While in operation the controller must be kept closed and secured.
Before starting the equipment, check all external bolts on the feeder assembly for tightness. Then, rotate
the control knob on the controller to a low counterclockwise position. Turn the switch to its “on” position
and the feeder will begin operating at a low rate of feed. Check the method of feeder support, making sure
it is substantial and the feeder is not touching any rigid objects or an adjacent structure.
CAUTION: When operating normally, the feeder should perform with a smooth even stroke. If a
loud “striking” noise occurs, immediately turn off feeder.
Striking is the result of the faces of the core and armature making contact. Striking can result in serious
damage to the unit! Refer to the Air Gap section of these instructions for corrective action.
With the feeder operating satisfactorily, load the trough with the material to be conveyed and adjust the
control knob to the desired output. Clockwise rotation will increase the feed rate; counterclockwise will
decrease the feed rate. The material will flow along the trough surface in a smooth controlled rate of feed
toward the discharge.
MAINTENANCE
WARNING: Before performing any maintenance work, the electrical power supply must be
disconnected at the safety disconnect switch and locked out.
Some materials, due to their nature, adhere to the trough surfaces. These deposits increase dead weight
to the feeder trough, and if permitted to build up excessively, will alter the natural frequency (tuning) of the
feeder. Material build-up on the trough should be removed as a daily practice. Look for material build-up at
the rear of the feeder trough, particularly around and under hopper openings.
A clean, dry compressed air supply is recommended for general cleaning of these units. Water is not
recommended.
CAUTION: Never oil the spring assembly. This destroys the clamping effect of the spring
pads against one another.
In the event repairs are necessary, take immediate action to avoid possible injury to personnel and
damage to the feeder parts from faulty operation. When ordering replacement parts, include all information
given on the nameplate.
